Baintech BTPS3000W 3000 Watt Pure Sine Wave Inverter

Clean, stable 240V AC power for tools, appliances, and sensitive electronics—anywhere you've got 12V battery power.

Product Overview

The Baintech BTPS3000W is a 3000 watt pure sine wave inverter designed to deliver manufacturer-specification power quality for demanding equipment. Unlike modified sine wave inverters that produce choppy waveforms, this unit generates smooth, grid-quality 240V AC power that runs motors cooler, starts equipment more reliably, and keeps sensitive electronics like laptops, medical devices, and digital equipment operating without interference or damage.

Built for serious off-grid applications including workshops, remote worksites, caravans, and expedition vehicles, the BTPS3000W handles everything from power tools and air compressors to microwaves and coffee machines. The pure sine wave output is essential for equipment with variable speed motors, laser printers, audio systems, and any device with microprocessor controls that can be damaged or malfunction on modified sine wave power.

The inverter features convenient front-panel controls with LED fault indicators, dual USB charging ports for phones and tablets, and optional remote control capability for mounting the switch in accessible locations. At 8.2kg, it's substantial but manageable for permanent installations in canopies, caravans, or marine applications where reliable 240V power is non-negotiable.

Features & Benefits

Pure Sine Wave Output for Equipment Protection: Generates clean, grid-quality power that matches household electricity. Critical for running variable speed tools, digital clocks, audio equipment, medical devices, and any electronics with sensitive microprocessors. Prevents the buzzing, overheating, and premature failure that modified sine wave inverters cause in motorized loads.

3000W Continuous Power Capacity: Handles substantial loads including circular saws, angle grinders, air compressors, microwaves, kettles, and multiple appliances simultaneously. Suitable for running a full camp kitchen setup or powering a remote workshop where mains power isn't available. Peak surge capacity handles motor starting loads.

Dual USB Charging Ports: Two 5V, 2.1A USB ports provide convenient phone and tablet charging without needing separate USB adaptors or wasting 240V output on small devices. Handy for keeping communication devices charged while running larger appliances.

Remote Control Capability: Optional remote switch port allows you to mount a remote ON/OFF switch in convenient locations—inside the cabin, at the camp kitchen, or wherever makes sense for your setup. No need to access the inverter directly to power up equipment.

Front Panel LED Diagnostics: Fault indicator LED turns red when issues arise, helping diagnose problems with input voltage, overload conditions, or thermal shutdown. Inverter indicator shows when equipment is receiving inverted AC power. Simple, at-a-glance status monitoring.

Thermal Management System: Forced ventilation with strategically placed vents maintains optimal operating temperature even under sustained high loads. Essential for Australian conditions where ambient temperatures can exceed 40°C and inverters are often installed in enclosed spaces.

Hardwired Terminal Options: For high-current applications, hardwire terminal block accommodates permanent installation without relying on standard plug connections. Suitable for fixed caravan installations or workshop setups where the inverter remains permanently mounted.

Chassis Grounding for Safety: Ground terminal ensures proper electrical safety grounding to vehicle chassis or earth ground, protecting users from shock hazards and reducing electrical noise interference with radios and other sensitive equipment.

Frequently Asked Questions

What's the difference between a pure sine wave and a modified sine wave?  Pure sine wave produces smooth, grid-quality power identical to household electricity, suitable for all equipment.

What size battery and cabling do I need for 3000W? At 3000W output, the inverter draws approximately 250A from your 12V battery under full load.

Can I run my caravan air conditioner on this inverter? Check your air conditioner's starting surge requirements and running wattage.

How long will my battery last running 3000W? Battery runtime depends on your battery capacity and load. 

Does this inverter need ventilation when installed? Yes, the inverter generates significant heat under load and requires adequate ventilation for cooling.
